PU LVERlZlNG-CARBURETER FOR PETROLEUM-MOTORS.

SPECIFICATION forming part of Letters Patent No. 733,695, dated July 14, 1903.

Application filed March 22, 1902. Serial No. 99,613. (No model.)

To aZZ whom it may concern:

Beit known that we, FERDINAND CHAERON and LEONCE GIRARDOT, citizens of the Republic of France, residing at 45 Avenue do la Grande Arme, Paris, in the Republic of France, have invented certain new and useful Improvements in the Construction of Pulverizing-Carbureters for Petroleum-Motors, of which the following is a specification.

It is well known that to obtain good carburization it is desirable to prevent the cooling produced in the jet or spray carburetors through the expansion of the gas. According to this invention such cooling is prevented by constructing the carburetor with a double wall or jacket in order that the hot water coming from the motor-jacket may circulate in the jacket of the carburetor previously to passing to the radiator. By this means the zone where the mixture of air and petrol is produced is kept at a favorable temperature for the carburization, and at the same time the water coming from the jacket of the motoris more cooled. To attain our object, it was necessary to take into consideration that the carburetor has to be easily unmountable, so

' as to allow access to itsinterior, and has also to be removably joined to the air-conducting pipes, to the petrol-feeding pipe, and to the pipe leading the combustible mixture to the motor. Furthermore, it is absolutely necessary to render the infiltration of water in the jacket of the carburetor quite impossible; otherwise the carburization would be immediately stopped.

The annexed drawings represent a form of construction of our hot-water-jacketed carburotor.

Figure 1 is a longitudinal section on line 1 2 of Fig. 2. Fig. 2 is a plan. Fig. 3 is a vertical section on line 3 4 of Fig. 2. Fig. 4 is a horizontal section on line 5 6 of Fig. 1.

The brass body of the carburetor comprises three separately-cast parts, each in one piece. These parts are, first, the carburetor, properly called, a, with its air-inlet pipe a; secondly, the tubular cap I), which closes at the outside and top part of the water-chamber surrounding the carburetor-chamber and constitutes at the same time the side or wall of the jacket surrounding the upper part of the air-inlet pipe, and, thirdly, the flange-joint c, which closes at the top part the waterchamber surrounding the air-inlet pipe and permits of the fixing of the pipe which directs the air to the carburetor. The drawings show clearly how these difioront parts are fixed and show that no communication can take place between the spaces where the gases circulate and the water-chamber.

The apparatus is fixed on a plate g,in which is made the bore 0, through which the petrol or the like passes to the carburetor-nozzle from an ordinary reservoir with constant level, and it is completed by the ordinary devices used in carburetors of this kind, the nozzle h and the conep, which, as shown on the drawings, may be in one piece with the stopper T, which closes the carburization-chamher at the top. The air arrives, therefore, in the carburetor by the pipe at, the petrol through nozzle h, and the combustible mixture goes to the motor through the pipe 5. The hot water of the circulating system onters the chamber-jacket at the top part at i and passes out at the lower part at c after having heated the carburetor.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

A jet or spray carburetor for petroleummotors comprising a carburetor-body a with a hot-water jacket, in combination with a tubular casing 11 which closes at the top the water-chamber surrounding the body of carburetor and which forms at the same time the wall of the jacket surrounding the top part of the air-inlet pipe at, a joint-flange c which closes at the top the water-chamber surrounding the air-inlet pipe and Which allows of fixing'to the carburetor the air-inlet pipe, a plate g to which is secured the body of the carburetor and in which is provided a petroleum-inlet conduit 0, and a nozzle h screwed in the plate 9 and leading to the carburization-chambor, substantially as and for the purpose set forth;

In witness whereof we have hereunto set our hands in presence of two witnesses.
